BACKGROUND OF THE INVENTION SUMMARY OF THE INVENTION An object of the present invention is to obtain a pipe having further improved structure decreasing the possibility of having stagnant drainage liquid collecting within the pipe normally impairing enjoyable taste to the smoker of the pipe.

Another object is to obtain a pipe structure and plug in combination facilitating removal of the plug and absorbed ingredients therein.

Anotherobject is, as a combination with an improved pipe, an improved disposable plug for a reservoir.

Another object is to obtain an improved plug means facilitating the removal of moisture from the pipe without soiling or dripping on surrounding areas.

Another object is to obtain a plug of improved total absorbency.

Another object is to obtain a tion of improved sanitation.

Another object is to obtain animproved plug of prolonged life collectable of greater quantities of liquid.

Other objects become apparent from the preceding and following disclosure.

One or more of the preceding objects are obtained by the invention as described hereafter.

Broadly the improved structure of the present sanitary and dry smoking pipe lies in a substantially linear smoke passage extending from the stem outlet inserted plug and pipe combinawithin the shank jack, extending to the pipe bowl, with the smoke passage being devoid of any obstructing structure of the pipe itself, and having adjacent the stem outlet of the stem-mouth piece a chamber within the shank of the pipe, the chamber preferably being of cylindrical shape with the longitudinal axis of the cylinder preferably being colinear with the longitudinal axis of the passage extending to the pipe bowl, and with a drainage reservoir passage extending at an angle to the shank passage and chamber withthe angle ranging from about to about 80 and the reservoir passage being substantially linear having within the reservoirv passage a removably inserted absorbent plug with a graspable end extending out of the, reservoir drainage exterior outlet port. The plug graspable end extends out a predetermined distance sufficient for gripping of the plug with the fingers for removal thereof from its inserted position. Although the jack end of the shank may define a receptacle open end to the linear passage running to the pipe bowl with the receptacle being of any desired or predetermined diameter, preferably the chamber is of a diameterthe same as the male insertportion of the mouth piece-stem thereby facilitating the cleaning of the entire smoke passage with an appropriate pipe cleaner. Also as a broad part of the improved invention, the shank of the stem and the smoke passage running to the bowl interior extend at a downwardly inclined angle relative to the mouth pieceend of the stern such that the moisture passing from the sm'okers mouth into the stem readily moves downwardly by the action of gravity into the smoke-passage chamber and into the reservoir passage, to thereby come in contact with the absorbent plug.

The invention also includes asa part thereof a plug which is of an absorbent composition tapered or angled at either end or at both ends such as a rhomboid length-wise cross-section, and in an alternative embodiment tapered. at neither end. In the combination of this pipe, the plug is of a sponge and/or absorbent nature whereby it withdraws the moisture from the reservoir chamber into the plug itself providing improved dry smoking devoid of the tobacco juices and saliva which would adversely affectthe taste of the smoke. Typically the plug combination is cardboard, compressed paper, rolled cardboard or paper, or the like, but may be cloth or other absorbent composition. Although the plug is elongated and may be of any desired design or shape, it preferably is of a cylindrical shape, but-for example may be in one embodiment of substantially squared cross-section, with the perimeter along the cross-section thereof having somewhat rounded walls. Also in one embodiment, the plug includes the above-noted preferably-annular rubberized coating near the finger-gripping end of the plug with the coating such that it facilitates the gripping as well as the sealing around the edges of the plug such that moisture does not escape from the pipe except through the breathing through-passage of the rubberized coating having the end of the absorbent composition mounted in and extending through the breathing passage of the annular rubberized coating: The plug composition includes a component and/or a coating and/or is inherently of a nature imparting a reasonable firmness or rigidity thereto, facilitatable of insertion and removal thereof from the reservoir passageqThe plug may in an alternative embodiment be a tapered tube open at its tapered insertable end.

THE FIGURES FIG. 5 is a longitudinal sectional view of a straight rolled or twisted firm paper moisture absorbent plug that may be used in lieu of the sponge plug 14 of FIGS. 1 to 4.

FIG. 6 is a side elevational view of a cardboard sponge plug tapered at its opposite ends to follow the bowl contour as illustrated in FIG/2.

FIG. 7 is a side elevational view of a paper cartridge plug similar to the plug of FIG. 5 but having a resilient annulus handle tip binder 18. 7

FIG. 8 is a longitudinal sectional view of a resilient rubber-like hollow liquid collection vessel plug having DETAILED DESCRIPTION OF THE INVENTION FIG. 1 illustrates an end view of a typical pipe 8 of the present invention, having pipe bowl 9, reservoir passage outer-port l3, and cylindrical plug 14.

FIG. 2 as taken along lines 2-2 of FIG. 1, illustrates the pipe bowl interior l0, shank l l, and stem 12 as well as the mouthpiece end 12a (FIG. 4) of the stem 12. The reservoir has a drainage outlet exterior port 13, the port can be seen in a cross-section view of the pipe bowl 9 having a shoulder 10a.

In the FIG. 4 embodiment, the port 13 extends from an underside 11a of the shank ll. Mountably inserted within the drainage reservoir passage 11b through the port 13 is a plug 14. FIG. 3 illustrates the end-view appearance of the FIG. 4 embodiment, such as bowl 9' and plug 14'.

As typically illustrated in FIG. 4, shank 11' the length of the is represented as llj, one half the distance from the shank end adjacent the stem is represented as 11m, and is measured from the half-way point lln to seven-eighths the length of the shank as indicated as 11k, the line representing 11k mark being represented by 11k. The line representing the end of the 11] line is represented as llj. 1

The distance 11h of the stem male insert llh into the shank jack receptacle smoke passage 11f is measured from linellhh to line 1 1g. The remaining chamber lle is represented by distance 1 1p, as measured between lines 11g and 11k. The end of the pipe shank 1] is located at 1112'. The narrow smoke passage lld extends from the bowl interior 9, continues as the chamber 1 1e, upon extending through the chamber end wall He. In the chamber lower wall or floor is the reservoir passage outlet llr communicating with the drainage reservoir passage llb and the passage llh exiting through reservoir exterior outlet port 13'. The exterior port 13 may be located at any point from line lln to 112, as represented by the measuring line llu. The line Ilt represents the extent of the measurement lld the measurement of one-fourth the outer width of the bowl at Ilw, as measured from the shank end at line llj. Line 12b defines the angle 12c which normally ranges from about 2 to 6 in the downward curvature of the shank-end of the stem 12 as compared to the mouthpiece end 1211 of the stem 12.

The chamber (i.e., the remaining length) length normally varies from a beginning point at possibly as close as about three-eighths inch from the shank end to a beginning point at about seven-eighths of the shank length, for a length ending at a point at about one-half to seven-eighths of the shank length to line lIk' preferably from a point at about one-half the shank length (at line lln) to about seven-eighths the shank length (at wall 111'). The reservoir outlet exterior port 13 is located at any point from about beneath the chamber to about seven-eighths the length of the shank (at line 11k), in a bottom side or face of an exterior shank wall. The area in which the reservoir drainage exterior port 13' may be located is defined by line llu. The forward edge of the exterior port may range toward the end of the bowl to about one-fourth the distanee of under the bowl, as represented by the line 11!. The outside diameter of the bowl 9 is indicated by the line 11w.

It should be noted that the rubberized composition of the annulus form 15 of (FIG. 7) preferably presses against the wall of the reservoir passage 1111 (when in .the inserted position) pressing at a forward point of the upper portion of the port, thereby facilitating the sealing function of the plug composition. Although the plug of the invention may be compressed matter or a solid structure, or of a sponge or rubber or foam material, typically twisted firm paper is advantageous, preferably tapered to a smaller diameter length at its insertable end. A plug typically varies from about three-eighths inch to about 1 /2 inch in length. Additionally however the rubberized annular coating 15 facilitates in the gripping of the plug for removal thereof from the exterior port. I

The angle 16 represents the angle of the longitudinal axis of the plug relative to the base 11a of the shank, this being the angle which may vary from about 10 to about I FIG. 5 absorbent plug corresponds to the FIG. 4 plug, and is a straight paper cartridge of about three-eighths to 1.5 inch.

FIG. 6 illustrates typically a cardboard tapered sponge plug, tapered at ends 17 and 17' to follow bowl contour.

FIG. 7 corresponds to the FIG. 5 embodiment except additionally including the resilient annulus tip 18.

FIG. 8 illustrates a resilient hollowed collectionvessel plug 19 having tapered open end 20.

Typically, in embodiments having a shoulder, the shoulder height varies from about one sixty-fourth up to about one-fourth the reservoir passage diameter.

Although the reservoir passage preferably is tubular with parallel opposite walls, the passage may taper inwardly.

It should be noted that any suitable or conventional absorbent composition may be employed for the absorbent plug, including non-absorbent materials which because of elasticity, and/or hydroscopic properties, and- /or perforations which serve to draw into the body pipe moisture, and that any suitable or conventional plastic or rubber having necessary heat stability may be utilized as the annulus, as within the spirit and scope of the present invention. Similarly other obvious variations and/or modifications are within the scope of the invention.
